I'm building a Crossrider extension. I've set up browser button in the background.js file using:
appAPI.browserAction.setResourceIcon('lock.png');
appAPI.browserAction.setPopup({resourcePath:'popup.html',
height: 300, width: 400});
I've also enabled browser button setting for all browsers: IE, Firefox, Chrome and Safari.
Browser icon shows perfectly in Firefox and chrome, but in IE(8,9) the icon doesn't show up.
Once I install the extension using the installer, it shows for first time when I launch Internet Explorer, but subsequently opening IE - there's no browser button shown at all in Internet Explorer.
